If you would like to complete story on the Kickboat contact me and check out the sight of www.waterstrider.com There seems to be a lot of gas in the air and a slight breeze from me can clear up all of the air in circulation.

From the pictures on the link it looks like a well built boat. My concern about the style would be when you get stuck on a rock in a river.

To me it seems like you would get a bunch of heavy water over the top and pushing onto you and all through your stuff. Sure it is self bailing but it seems like the sides should be higher -- unless the intention is for smaller rapids, then it would probably be good for that. Just an opinion.

It does look like it is well built though. I am sure that for some applications it might be very good...

Your coments are valid for someone who has not used the raft. that is not a problem because the ovid shape of the tubes prevents that from happening and the raft does not get hung up on most rocks unless the water is less than 3 inches deep.
Thanks,
